3月10日，國家電網±500千伏寶德直流工程(cheng)極Ⅱ及雙極系統(tong)調試(shi)正(zheng)式啟動，整個調試(shi)時間約17天。
系(xi)統調(diao)試(shi)是在換流站(zhan)分系(xi)統試(shi)驗(yan)和站(zhan)系(xi)統試(shi)驗(yan)完成后(hou)，在各種實際(ji)運行(xing)工況(kuang)下對換流站(zhan)的(de)交流、直流設備進行(xing)性(xing)能試(shi)驗(yan)的(de)一項環節(jie)。系(xi)統調(diao)試(shi)主(zhu)要(yao)是校驗(yan)站(zhan)內一次設備狀(zhuang)態、二次設備動作的(de)可靠性(xing)及站(zhan)間通信的(de)正確性(xing)等。系(xi)統調(diao)試(shi)結束后(hou)，工程即可投入試(shi)運行(xing)。
寶德直流(liu)工程(cheng)系統(tong)調(diao)試(shi)(shi)(shi)的內(nei)容包括：初始化運(yun)行(xing)(xing)試(shi)(shi)(shi)驗(yan)(yan)、保(bao)護跳閘試(shi)(shi)(shi)驗(yan)(yan)、直流(liu)穩態運(yun)行(xing)(xing)試(shi)(shi)(shi)驗(yan)(yan)、功(gong)(gong)率升降試(shi)(shi)(shi)驗(yan)(yan)、階躍響應試(shi)(shi)(shi)驗(yan)(yan)、控制(zhi)模(mo)式轉換、裕(yu)度補償試(shi)(shi)(shi)驗(yan)(yan)、無功(gong)(gong)功(gong)(gong)率控制(zhi)試(shi)(shi)(shi)驗(yan)(yan)等共計132項試(shi)(shi)(shi)驗(yan)(yan)，內(nei)容全(quan)面涵(han)蓋極II單極和系統(tong)雙極的低(di)功(gong)(gong)率、大功(gong)(gong)率方(fang)式下(xia)的運(yun)行(xing)(xing)控制(zhi)試(shi)(shi)(shi)驗(yan)(yan)和故障擾動試(shi)(shi)(shi)驗(yan)(yan)。
據相關(guan)調(diao)試(shi)人員(yuan)介(jie)紹(shao)，寶德直(zhi)流工(gong)(gong)(gong)程是首次采用(yong)100%國(guo)產化設(she)(she)備建成的(de)輸電工(gong)(gong)(gong)程，有很多(duo)設(she)(she)備是首次應用(yong)到直(zhi)流場中，給系統(tong)(tong)調(diao)試(shi)工(gong)(gong)(gong)作(zuo)帶來了(le)壓力。此外(wai)，為確保該(gai)工(gong)(gong)(gong)程4月中旬正式投(tou)運，整個系統(tong)(tong)調(diao)試(shi)時間由原來的(de)40天縮短(duan)到17天，這(zhe)同樣增加了(le)調(diao)試(shi)工(gong)(gong)(gong)作(zuo)的(de)難度。上述(shu)情況(kuang)要求調(diao)試(shi)人員(yuan)以更仔細的(de)態度、更嚴格的(de)要求來測試(shi)設(she)(she)備和系統(tong)(tong)。
本(ben)次調(diao)(diao)(diao)(diao)試(shi)(shi)由國網直流(liu)建(jian)設分公司組織協調(diao)(diao)(diao)(diao)，中國電力科學(xue)研究(jiu)院擔任(ren)系統(tong)調(diao)(diao)(diao)(diao)試(shi)(shi)單位，各安裝單位、廠(chang)家等配合。直流(liu)建(jian)設分公司高度(du)重視(shi)本(ben)次調(diao)(diao)(diao)(diao)試(shi)(shi)工(gong)作，該公司有(you)關領(ling)導親(qin)臨現(xian)場(chang)指(zhi)揮(hui)調(diao)(diao)(diao)(diao)試(shi)(shi)工(gong)作，協調(diao)(diao)(diao)(diao)解(jie)決調(diao)(diao)(diao)(diao)試(shi)(shi)過程中遇(yu)到(dao)的各種技(ji)術問題，確保工(gong)程項目在調(diao)(diao)(diao)(diao)試(shi)(shi)階段運轉高效規范。電科院調(diao)(diao)(diao)(diao)試(shi)(shi)人員分兩(liang)班(ban)輪崗(gang)，加(jia)班(ban)加(jia)點進(jin)行試(shi)(shi)驗。
截至3月15日，寶德(de)直(zhi)流工程現(xian)場共(gong)進行(xing)(xing)了(le)71項(xiang)試(shi)驗(yan)，極(ji)Ⅱ低功率試(shi)驗(yan)項(xiang)目均已完成，其余的現(xian)場調試(shi)項(xiang)目正在緊張有序進行(xing)(xing)。
